Kinetic energy, work pirnciple. (?)

[heelp]

a base ball (m= 140g) traveling 32m/s moves a fielder's glove backward 25cm when the ball is caught. What was the average force exerted by the ball on the glove?



since w=f||d would it make sense if the average force is f= d/w
I know force =ma but I don't see how to apply it in this problem. I also know that work =m *h* g. but these informations doesn't help me.

you heelp would be appreciated

Maybe the kinetic energy of the ball would be a handy piece of information?

The ball decelerated to rest over a distance of 25cm. It's plain old equations of motion.

Edit: Just noticed the title of this thread. You'll get the same answer if you use kinetic energy and w = f*d.
